Got rid of strange animation when the bubble is resized while reloading on Safari

safari/ext/popup.js

 (function()
 {
   // Safari will load the popover once, and then show it everytime the icon is
   // clicked. While Chrome loads it everytime you click the icon. So in order to
   // make the popover show the right state and details we have to reload it
   // everytime it is shown for a different tab. Also we have to reload the
   // popover when the background page wasn't ready yet, since we have to access
   // the background page in the popover.
   var backgroundPage = safari.extension.globalPage.contentWindow;
   var readyState = backgroundPage.document.readyState;

   safari.self.addEventListener("popover", function()
   {
     if (activeTab != safari.application.activeBrowserWindow.activeTab || readyState != "complete")

       document.documentElement.style.display = "none";
       document.location.reload();
     }
   });
 
 
   // Safari doesn't adjust the size of the popover automatically to the size
   // of its content, like when the ad counter is expanded/collapsed. So we add
   // event listeners to do so.
   var updateSize = function()
   {
-    safari.self.width = document.body.offsetWidth;
